Re: Cannot launch hart RT UOS when running Ubuntu as SOS

Hi Liu and Geoffroy,

Right, I had forgotten to copy acrn.efi to the EFI partition after re-compiling, thanks for reminding me. With that things move forward a bit, but I still get errors:


Version info:

$ acrn-dm -v
DM version is: 1.4-unstable-bcefd673 (daily tag:acrn-2019w47.1-140000p), build by ubuntu@2020-01-09 09:45:17

ubuntu@nuc:~$ uname -a
Linux nuc 4.19.78-98.iot-lts2018-sos #1 SMP PREEMPT Mon Nov 18 09:22:10 PST 2019 x86_64 x86_64 x86_64 GNU/Linux

I have not been able yet to get output from the serial port, unfortunately.


I see there an hvlog error which I do not know if it is relevant or not:

Hi Alfonso

Could you please share acrn.efi and acrn-dm commit info?

 

With following steps:

  1. run “acrn-dm -v” in sos
  2. run “version” in HV console

We need them to reproduce this issue.

Thanks!

 

BR.

Hi Alfonso,

You are using default launch_hard_rt_vm.sh, right?

Maybe, it is SDC(by default) scenario for your acrn.efi,

Please refer following patch:

 

diff --git a/hypervisor/arch/x86/Kconfig b/hypervisor/arch/x86/Kconfig

index 41a78fe7..386a074b 100644

--- a/hypervisor/arch/x86/Kconfig

+++ b/hypervisor/arch/x86/Kconfig

@@ -1,6 +1,6 @@

choice

        prompt "ACRN Scenario"

-       default SDC

+       default INDUSTRY

        help

          Select the scenario name to load corresponding VM configuration.

 

Then;

 

cd ~/acrn-hypervisor

make

sudo make install

 

And try again.

 

I tried with that, but no difference in the traces :-/.

Actually I had already tried with 'make all BOARD=nuc7i7dnb SCENARIO=industry', which I guess i the same.

 

 

Thanks!

Thanks

Hi,

I have set-up Ubuntu as service OS by following the instructions in https://projectacrn.github.io/latest/tutorials/using_ubuntu_as_sos.html. ACRN is recognized as hypervisor and all looks good in principle. However, after that I followed the instructions on how to start an RT UOS and things fail:

$ sudo /usr/share/acrn/samples/nuc/launch_hard_rt_vm.sh

cpu1 online=1

cpu2 online=1

cpu3 online=1

pm by vuart node-index = 1

SW_LOAD: get ovmf path /usr/share/acrn/bios/OVMF.fd, size 0x200000

vm_create: hard_rtvm

VHM api version 1.0

failed to create VM hard_rtvm


The kernel output is:

Any hint on what might be going wrong and instructions on how to debug? I followed previously the tutorial for Clear Linux and was able to launch the RT image. I am using a NUC7i7DNH device.

Thanks!
Alfonso
